SasuSaku: Faceless Desire

Sakura is Sasuke's new personal assistant. Sakura is also his closest friend, unbeknownst to them both. When the duo is randomly connected via a new phone app that allows people to talk anonymously with strangers, they immediately click. Here's the problem: the duo doesn't get along in real life, and Sasuke thinks his friend is a man.
